Fine Grade Yellow Poly-Clay.

Yellow poly-clay has been a staple product of detailers for many years, and for good reason… it is great value, has a good consistency and works remarkably well. Being a fine grade clay, there is also less chance of marring, although clay lube is still recommended during use. This economical 55g bar is supplied in a resealable polybag to keep it fresh and free from contamination.

Product Reviews

If ever there was a product that does excactly what the description says, this is it.
I don't exactly have a very expensive car so spending a bomb on a clay bar isn't really what I wanted which means this was the perfect product.
My car is Japanese so the paint is said to be quite soft but using plenty of lube I haven't marred it at all so I am more than satisfied.
